Jason Collins is set to become the NBA's first active openly gay player.
But his only focus is playing basketball, saying "I don't have time to really think about history right now."
Collins signed a 10-day contract with the Brooklyn Nets earlier Sunday and was to be in uniform for their game in Los Angeles against the Lakers. The 35-year-old center revealed at the end of last season he is gay, but he was a free agent and had remained unsigned.
With a need for another big man, the Nets turned to the 7-foot Collins, who helped them reach two NBA Finals in the early 2000s.
Collins says "the pressure is playing in an NBA game ... so I think that's enough pressure right there."
